This time, I can't just ifndef the header file that defines my
structure.
So I have two classes that I've managed to dodge around this problem

to fail because of multiple definitions of the same type. That's why
it's standard practice to write all headers like this:
// SomeClass.hh
#ifndef SOME_CLASS_HH
#define SOME_CLASS_HH
class SomeClass

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
